There are Golden Rules for being a good mentee.
Here are four key recommendations for best practice.
1. Select the right mentor(s)
- finding suitable mentors is a process of judgement and learning, there needs to be congruence between your goals and the skills and knowledge of the mentor
 - Find someone with content expertise, or influence in a field, who has a wide network of contacts
 - Someone in the top of their field isn't necessarily a good mentor, personal attributes (patience) and values (altruism) are fundamental to a good relationship. You should like, respect and trust your mentor.
 
2. Be respectful of your mentor's time and manage it wisely
- Be proactive in scheduling appointments, plan a regular slot
 - Plan for meetings by setting out agendas and prioritising discussion points
 - Include a timeline to schedule each item so the both of you focus on what is important
 - Propose solutions to help your mentor decide which answer may be best ("managing up")
 - request actions before meetings to help your mentor prepare "Please review X so we can discuss at our meeting"
 
3. Communicate efficiently and effectively
- begin with honest conversations regarding your goals and aspirations
 - include a written plan of short and long term goals, which helps share a vision of success with your mentor
 - Clarify roles and expectations on both sides to minimise conflict and disappointment.
 - establish regular cadence of communication that includes goals and progress towards them, for example: summary of current project status, including progress and problems, discussion of new projects, etc.
 - pay attention to your "talking-to-listening ratio", it should be less than one. You should be listening more than you are talking.
 - Send focused messages with brief background that can be answered with "yes" or "no" are ideal
 
4. Be engaged, energising, and collaborative
- avoid emotionally draining behaviours, such as complaining, pessimism, and "snarking" about others.
 - Show that you are mature and genuinely open to learning
 - be an energy donor, not an energy recipient
 - help drive projects forward, be proactive, and accept all comments as important learning opportunities
 - Be a "closer" : someone who follows through on tasks in timely fashion and at a high standard.
 - Be generous and honest in giving others credit, you're working with not just your mentor, but other colleagues and the wider scientific community.
